‘Tis the season of new smartphone rumors, HTC is said to be working on what could be a rather amazing phone.

According to the fairly reliable @upleaks Twitter account, HTC is building a follow-up to the One M8 with an 64-bit Snapdragon 810 processor, which has four 2GHz high-performance cores four 1.5GHz power-efficient cores. Code-named “Hima,” the phone is rumored to have a five-inch, 1920×1080 display a 20.7-megapixel rear camera. The front-facing camera is listed as either a 13-megapixel or 4-megapixel “Ultraxel” option.

HTC Hima:S810 2.0GHz*4+1.5GHz*4, 3GB RAM, 5″ FHD, VoE/CA/E Cat.6, 20.7Mfront 13Mor Ultraxel 4M, 2840mAh, Android 5.0/Sense 7.0:)

Other tweets say it’s coming in h 2015 to all major U.S. carriers. The Hima is currently being tested in a carrier lab, will be a part of a family of phones announced during Mobile rld Congress, @upleaks says.

The Snapdragon 810 processor has tons of memory bwidth (two 64-bit channels of DDR4 at 1600MHz, double the bwidth of today’s top-end Snapdragon 805), a more powerful Adreno 430 G. This should make resource-intensive games apps fly with the greatest of ease on a 1080p screen.

Other rumored specs include a 2840 mAh battery Android 5.0, with a new version of HTC’s Sense custom user interface.

ablet fans will be a little disappointed in the screen size, as while super-sized phones may be difficult to hle at times, it’s hard to argue with their utility.

y this matters: ile HTC already shipped a phone with a 64-bit processor in the Desire 510, it was using a 64-bit C built for low-range models, didn’t ship with a version of Android that supports 64-bit processors. So we’ve yet to see how fast fluid the experience could really be on a high-end, 64-bit phone. ile the benefits of such technology have been rather dubious so far, we’re excited to see how this phone turns out what real-world performance is really like.
